CHURN.

SPECIFICATION forming part of Letters Patent No. 438,482, dated October 14, 1890.

Application tiled April 11.1..l 1890. Serial No. 347,922. (No model.)

To all whom, t may concern.-

Bp it known that I, ELLswoRTH D. MID- DLEKAUFF, a citizen of the United States, residing at Stockton,in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The gure is a side elevation of my improved churn, a part of the side of the bowl being broken out to display the dasher apparatus.

My invention` has relation toimprovements in churns and it consists in the construction, arrangement, and adaptation of devices, as will be hereinafter more fully set forth and claimed.

Similar letters of reference indicate correspondin g parts.

A is the foot-stand of the frame, to which is attached a standard A', to the front of which at its top is attached a block A2. A way or bearing for a shaft C is provided at the head of the standard A', through such standard, and through the block A2. At the outer end of this shaft C is attached a flywheel D, provided with an operating-handle D and a groove-pulley D2 in case treadlepower is desired to be used. To the summit of the standard A and block A2 is attached a spring-steel bar F, the outer end of which forms the bearing of a vertical dasher-shaft G, which at its lower end is journaled in a step J2 at the bottom of the churn-bowl B, which is seated on the foot-stand A, and is secured in position by side blocks a and front block a', the latter being hinged to the stand A. A hollow vertical shaft G encircles the shaft G and is supported in position at its foot by a collar J, secured to the shaft by a set-screw. The lower cross-bar I-I ofthe dasher is attached near the bottom of the bowl to the shaft G by a set-screw h. To the bar H are attached four short blades I. The

Long vertical blades I are attached between each two of the upper blades I by screws t', and are provided with two or more holes each, so as to be vertically adj u stable.

The gearing to impart motion to the shafts G and G consists of a large bevel-gear D3,

attached to the end of the shaft C, and meshes with a bevel-pinion E at the top of the shaft G, just beneath the end of the spring-bar F, and with a similar bevel-pinion E', attached to the hollow shaft G.

By turning the handleDor treadle-pulley D2, attached to lthe ily-wheel D, the shaft C and its bevel-gear D3 impart motion to the bevel-pinions E and E and their respectivelyattached shafts G and G', causing the dasherbars H and H to rotate in opposite directions, whereby a most thorough agitation of the cream within the bowl of the churn is produced.

The long blades I being vertically adjustable on the bar I-I may be made long or short when operated, and thus be accommodated to a large or small quantity of cream within the bowl B. The cross-bar H may be moved up and down on the shaft G to accommodate any changes in the position of the blades I.

The cover K is provided with a covered slot K.

To remove the dashers and the shafts Gv and G from the bowl B, the spring-bar F is raised at its outer end, releasing the shaft G. The cover K is then removed, the slot K permitting it to pass the shaft G. The dasher and shafts may then be lifted from the bowl B. The bowl B may be removed from the foot-stand A by turning back the hinged block a.

Having thus described my invention, what I claim is- In a churn having a double concentric dasher operated by a gear engaging gears on each dasher-shaft, the spring F, secured to standard A and having a bearing for the shaft G, and the slotted cover K, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
